BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to an apparatus and method for connecting to a device in a wireless terminal. More particularly, the present invention relates to an apparatus and method for more conveniently connecting to a desired device in a communication mode of a wireless terminal.

2. Description of the Related Art

Wi-Fi Peer to Peer (Wi-Fi P2P) or Wi-Fi Direct technology is technology for providing a direct connection between Wi-Fi terminals by using an existing Wi-Fi interface without having to communicate with an Access Point (AP) that is an existing medium in infrastructure networks.

The existing Wi-Fi technology generally relates to a connection to the Internet through an AP. Accordingly, there has been a lack of development to Wi-Fi technology as it relates to direct communication between Wi-Fi terminals.

This lack has been somewhat supplemented through the use of Bluetooth technology. However, Bluetooth technology has certain limitations associated with a transmission distance and a transmission speed. Consequently, Wi-Fi P2P technology is expected to cover the portion of communication between terminals that Bluetooth does not supplement.

Although the existing Wi-Fi technology also supports a direct connection in an Ad-hoc mode, the Ad-hoc technology has not been effectively commercialized. In other words, the Ad-hoc technology has rarely been used in practice due to various disadvantages associated with the Ad-hoc technology. For example, disadvantages associated with the Ad-hoc technology include vulnerability in security, power consumption, and limited transmission speeds (e.g., throughput traffic being limited to 11 Mbps).

The Wi-Fi Direct technology supplements vulnerability in security by supporting a security mode of Wi-Fi Protected Access 2 (WPA2) and supports simpler connectivity between Wi-Fi terminals than before by using a Wi-Fi Simple Configuration (WSC). In addition, the Wi-Fi Direct technology drastically improves throughput compared with the Ad-hoc technology by supporting wireless networking standard IEEE 802.11n and by using an enhanced power consumption algorithm.

A Wi-Fi Direct function is based on IEEE 802.11, legacy Wi-Fi standards, is compatible with existing Wi-Fi terminals, and can be easily upgraded without a change in hardware.

A Peer to Peer (P2P) group indicates a set of Wi-Fi terminals connected to each other by using the Wi-Fi P2P technology. Assuming that devices are connected on a one-to-one basis, one device operates as a Group Owner (GO) and the other device operates as a Group Client (GC). In this case, the GO terminal functions as a Wireless Local Area Network (WLAN) AP and the GC terminal functions as a WLAN station.

Such a role of each P2P terminal is determined by using a P2P-only protocol, (i.e., GO Negotiation, in a Wi-Fi P2P connection process).

The generation of a P2P group based on the Wi-Fi P2P technology can be achieved by a 1:1 connection or a 1:N connection, and the number of acceptable GCs is determined based on the capability of a GO terminal.

In a Wi-Fi P2P connection process, devices are searched for through a Device Discovery process, and a Provision Discovery process is performed with a device desiring connection from among the searched devices.

The Provision Discovery process is a process of informing the device desiring connection of a connecting method, and a Web Service Connector (WSC) connection method includes a Push Button Configuration (PBC) method performed in response to a button input and a Personal Identification Number (PIN) method performed in response to a PIN number input.

Accordingly, a device which requests Provision Discovery transmits a message associated with a desired connection method. A device which has received the message corresponding to another device's request for Provision Discovery informs a user thereof of the message reception through a pop-up window.

The pop-up window displayed in response to receipt of a message corresponding to another device's request for Provision Discovery contains information, such as a device name of the device which has requested Provision Discovery. The pop-up window allows the user of the device which has received the message to determine whether the connection is accepted and whether to enable a WSC.

After the Provision Discovery process, a GO Negotiation process is performed to determine roles of the devices. A device determined to be a GO operates as an AP, and a device determined to be a GC operates as a Wi-Fi station.

When the device roles, GO and GC, are determined, the two devices complete a P2P connection by exchanging authentication information, such as authentication type, encryption type, network key, and Service Set identifier (SSID), through a Provisioning process.

However, every time connection to a device is performed through the Wi-Fi P2P connection process, a desired device should be selected through the Device Discovery process, and the above-described connection processes should be performed. In addition, when no desired device is discovered in the Device Discovery process, it is inefficient and burdensome to repeatedly perform the Device Discovery process until a desired device is discovered.

Accordingly, there is a need for a method and apparatus for connecting to a device in a wireless terminal to conveniently perform a Wi-Fi Direct connection while exchanging device information for a communication connection to a desired device through near distance communication of the wireless terminal.

The above information is presented as background information only to assist with an understanding of the present disclosure. No determination has been made, and no assertion is made, as to whether any of the above might be applicable as prior art with regard to the present invention.

In the exemplary embodiments of the present invention, although a Wi-Fi Peer to Peer (Wi-Fi P2P) communication mode is described as a communication mode by which a wireless terminal may establish a connection with a device as an example, the present invention may be applied to all communication modules for performing a data communication function by a connection through a device search as well as the Wi-Fi P2P communication mode.

FIG. 1 is a block diagram of a wireless terminal according to an exemplary embodiment of the present invention.

Referring to FIG. 1, a Radio Frequency (RF) unit 123 performs a wireless communication function of the wireless terminal. The RF unit 123 includes an RF transmitter for up-converting a frequency of a transmission signal and for amplifying the up-converted transmission signal and an RF receiver for low-noise amplifying a received signal and for down-converting a frequency of the amplified received signal. A data processor 120 includes a transmitter for coding and modulating the transmission signal and a receiver for demodulating and decoding the received signal. In other words, the data processor 120 may include a modem and a codec. The codec includes a data codec for processing packet data and the like, and an audio codec for processing an audio signal such as voice. An audio processor 125 plays a received audio signal output from the audio codec in the data processor 120 and transfers a transmission audio signal picked up by a microphone to the audio codec in the data processor 120.

A key input unit 127 includes alphanumeric keys for inputting alphanumeric information and function keys for setting various functions. As an example, the key input unit 127 may include input buttons, a touchscreen and/or the like.

A memory 130 may include a program memory and a data memory. The program memory may store programs for controlling a general operation of the wireless terminal and programs for controlling the establishment of a Wi-Fi P2P connection to a desired device through near distance communication according to an exemplary embodiment of the present invention. In addition, the data memory may temporarily store data generated while the programs are executed.

A controller 110 controls the overall operation of the wireless terminal. For example, the controller 110 may be operatively connected to the various units and modules of the wireless terminal.

According to an exemplary embodiment of the present invention, the controller 110 controls a near distance communication module 180 (e.g., a Near Field Communication (NFC) module) to exchange device information with a specific device contacted through the near distance communication module 180 and to perform a Wi-Fi P2P connection to the specific device based on the exchanged device information.

In addition, when a near distance communication with a specific device is connected through a contact with the specific device on a Wi-Fi communication connection setup screen of the wireless terminal, the controller 110 controls the wireless terminal to automatically switch to a Wi-Fi P2P mode by enabling a Wi-Fi P2P function.

In this case, when the Wi-Fi P2P function of the specific device including a near distance communication module is disabled, if the near distance communication is connected through the contact with the wireless terminal, the specific device also automatically switches to the Wi-Fi P2P mode by enabling the Wi-Fi P2P function.

In addition, the controller 110 controls the near distance communication module 180 to exchange a Media Access Control (MAC) address with the specific device and to simultaneously perform a device search operation in the Wi-Fi P2P mode.

In addition, as a result of the device search operation, if the specific device is displayed on a display unit 160 on which the device search result is displayed, that is, if a device having a MAC address received from the specific device exists among searched devices, the controller 110 controls the near distance communication module 180 to perform a role determining process and an authentication information exchanging process with the specific device. Accordingly, the controller 110 controls the wireless terminal to perform a Wi-Fi P2P connection to the specific device.

The existence of the specific device among the searched devices indicates that device information for the Wi-Fi P2P connection has been exchanged. Thus, the Wi-Fi P2P connection may be performed by performing the role determining process and the authentication information exchanging process with the specific device already selected through a contact as a device desiring the Wi-Fi P2P connection.

In addition, as a result of the device search operation, if the specific device is not displayed on the display unit 160 on which the device search result is displayed, that is, if a device having the MAC address received from the specific device does not exist among the searched devices, then the controller 110 controls the near distance communication module 180 to exchange device information for the Wi-Fi P2P connection with the specific device. After completing the role determining process and the authentication information exchanging process with the specific device based on device information received from the specific device, the controller 110 controls the near distance communication module 180 to connect communication to the specific device through Wi-Fi Direct communication.

Thus, by using the device information for the Wi-Fi P2P connection that has been received from the specific device through the near distance communication, the Wi-Fi P2P connection may be performed by performing the role determining process and the authentication information exchanging process with the specific device already selected through a contact as a device desiring the Wi-Fi P2P connection.

According to another exemplary embodiment of the present invention, the controller 110 controls the near distance communication module 180 to exchange a MAC address and device information with a specific device contacted through the near distance communication module 180 and to perform a Wi-Fi P2P connection to the specific device based on the exchanged MAC address and device information without performing the device search process, the role determining process, and/or the authentication information exchanging process with the specific device.

A Wi-Fi module 170 provides a near distance wireless communication function conforming to the IEEE 802.11 standard. According to exemplary embodiments of the present invention, the Wi-Fi module 170 allows a user of the wireless terminal to form (or create) a Wi-Fi P2P group to use a data exchange function and others.

According to exemplary embodiments of the present invention, the near distance communication module 180 is a communication module for transferring data between devices within a near distance. The near distance communication module 180 exchanges a MAC address and device information for a Wi-Fi P2P connection with a specific device contacted according to an exemplary embodiment of the present invention by being communication-connected to the specific device. According to an exemplary embodiment of the present invention, the near distance communication module 180 may be a Near Field Communication (NFC) module.

The wireless terminal may also include a camera unit 140. The camera unit 140 includes a camera sensor for capturing image data and converting the captured optical signal into an electrical signal, and a signal processor for converting an analog image signal captured by the camera sensor into digital data. The camera sensor is assumed herein to be a Charge-Coupled Device (CCD) or a Complementary Metal Oxide Semiconductor (CMOS) sensor, and the signal processor may be realized by a Digital Signal Processor (DSP). The camera sensor and the signal processor may be realized in an integrated manner or in a separated manner.

The wireless terminal may include an image processor 150 that performs Image Signal Processing (ISP) for displaying image signals output from the camera unit 140 on the display unit 160. The ISP performs functions such as gamma correction, interpolation, spatial variation, image effects, image scaling, Automatic White Balance (AWB), Automatic Exposure (AE), and Automatic Focusing (AF). For example, the image processor 150 processes the image signals output from the camera unit 140 on a frame basis, and outputs the frame-based image data according to the characteristics and size of the display unit 160. The image processor 150, which includes a video codec, compresses frame image data displayed on the display unit 160 by preset coding, and restores (or decompresses) the compressed frame image data into its original frame image data. As an example, the video codec may include a JPEG codec, MPEG4 codec, Wavelet codec, and/or the like. Assuming that the image processor 150 includes an On-Screen Display (OSD) function, the controller 110 may control the image processor 150 to output OSD data according to the size of a screen on which the data is displayed.

The display unit 160 displays an image output from the image processor 150 and user data output from the controller 110 on a screen. The display unit 160 may include a Liquid Crystal Display (LCD), and in this case, the display unit 160 includes an LCD controller, a memory for storing image data, and an LCD panel. The display unit may serve as an input unit with a touch screen, and in this case, the display unit 160 may display the alphanumeric keys of the key input unit 127. For example, the LCD may include a touch screen which may also serve as the key input unit 127.

A process of connecting to a device in the wireless terminal is described in detail with reference to FIGS. 2 and 3.

FIG. 2 is a flowchart illustrating a process of Wi-Fi P2P connecting to a desired device performed by a wireless terminal, according to an exemplary embodiment of the present invention.

This exemplary embodiment of the present invention is described in detail with reference to FIG. 1.

Referring to FIG. 2, at step 201 a Wi-Fi P2P setup screen of the wireless terminal is displayed by the display unit 160. At step 202, the controller 110 determines whether the wireless terminal is connected to a specific device desiring a Wi-Fi P2P connection through the NFC module 180 via near distance communication. In other words, the controller 110 determines whether the near distance communication module 180 is connected to a specific device when the wireless terminal contacts with the specific device. If the controller 110 determines that the wireless terminal is connected to a specific device via near distance communication, then the controller 110 proceeds to step 203 to automatically switch to the Wi-Fi P2P mode by enabling the Wi-Fi P2P function of the wireless terminal. Otherwise, if the controller 110 determines that the wireless terminal is not connected to a specific device via near distance communication, then the controller proceeds to perform other functions.

Further, at step 203, if the Wi-Fi P2P function of the specific device is disabled, the specific device may automatically switch to the Wi-Fi P2P mode by enabling the Wi-Fi P2P function of the specific device through the near distance communication connection to the wireless terminal.

If the near distance communication between the wireless terminal and the specific device is connected through the NFC module 180, then the controller 110 exchanges a MAC address with the specific device and simultaneously performs a device search in step 204.

At step 205, the controller 110 determines, as a result of the device search, whether a device having the MAC address received from the specific device exists among the searched devices. If the controller 110 determines that a device having the MAC address received from the specific device exists among the searched devices, then the controller 110 proceeds to step 207 to determine roles with the specific device. The controller 110 further proceeds to step 208 to exchange authentication information with the specific device. The controller 110 then proceeds to step 209 to establish a Wi-Fi P2P connection with the specific device.

The existence of the specific device among the searched devices indicates that device information for the Wi-Fi P2P connection has been exchanged. In addition, the near distance communication connection of the wireless terminal to the specific device indicates that the wireless terminal has already selected the specific device as a device desiring the Wi-Fi P2P connection. Thus, if the specific device exists among the searched devices, the Wi-Fi P2P connection may be performed by performing the role determining process and the authentication information exchanging process with the specific device.

However, at step 205, if the controller 110 determines, as a result of the device search, that no device having the MAC address received from the specific device exists among the searched devices, then the controller 110 proceeds to step 206 to exchange device information for the Wi-Fi P2P connection with the specific device through the NFC module that corresponds to the near distance communication module 180.

Thereafter, the controller 110 proceeds to step 207 to determine roles with the specific device and to step 208 to exchange authentication information with the specific device. The controller 110 then proceeds to step 209 to establish a Wi-Fi P2P connection with the specific device.

FIG. 3 is a flowchart illustrating a process of Wi-Fi P2P connecting to a desired device performed by a wireless terminal, according to another exemplary embodiment of the present invention.

This exemplary embodiment of the present invention is described in detail with reference to FIG. 1.

Referring to FIG. 3, at step 301 a Wi-Fi P2P setup screen of the wireless terminal is displayed by the display unit 160. At step 302, the controller 110 determines whether the wireless terminal is connected to a specific device desiring a Wi-Fi P2P connection through the NFC module 180 (e.g., the near distance communication module 180). In other words, the controller 110 determines whether the near distance communication module 180 is connected to a specific device when the wireless terminal contacts with the specific device. If the controller 110 determines that the wireless terminal is connected to a specific device via near distance communication, then the controller 110 proceeds to step 303 to automatically switch to the Wi-Fi P2P mode by enabling the Wi-Fi P2P function of the wireless terminal. Otherwise, if the controller 110 determines that the wireless terminal is not connected to a specific device via near distance communication, then the controller 110 proceeds to perform other functions.

Further, at step 303, if the Wi-Fi P2P function of the specific device is disabled, the specific device may automatically switch to the Wi-Fi P2P mode by enabling the Wi-Fi P2P function of the specific device through the near distance communication connection to the wireless terminal.

If the near distance communication between the wireless terminal and the specific device is connected through the NFC module (e.g., the near distance communication module) 180, then the controller 110 exchanges a MAC address and device information for a Wi-Fi P2P connection with the specific device in step 304.

In step 305, the controller 110 establishes a Wi-Fi P2P connection with the specific device based on the MAC address and the device information for the Wi-Fi P2P connection that have been received from the specific device without performing a device search process, a process of determining roles with the specific device, and a process of exchanging authentication information with the specific device.

As is apparent from the foregoing description, the proposed apparatus and method for connecting to a device in a wireless terminal, by which communication is connected through a contact between devices including a near distance communication module, maximize the utilization of Wi-Fi P2P and provide convenience in connection of communication with only a contact with a desired device. In addition, because accessibility that must be accompanied by a user's intention is required for a mutual contact between devices including a near distance communication module, there is a big advantage even in a problem related to security
